The amount of work that they did in one week was far beyond what we had anticipated they would be able to accomplish, and would have taken us 5-6 weeks on our own, at least. We're so grateful for the work they did for us as it alleviated a lot of stress and their quality of work is great."

"RT Total Lawn made the process from inquiry to installation easy. Sara responded to my Angie’s request, answered a few questions, then came out with owner Rafael to do an estimate.

When done, RT’s crew did a thorough clean up and Rafael and Sara came back to do a walk through. I am 100% satisfied and look forward to working them on other projects.

We are a new local business with 30 years of experience in the industry. We can act as General contractors on a large project or take on smaller sub-contracts. Depending on the job we bill for time and materials, or a lump sum total with 40%-50% due at signing of the contract
"Paul Burlingame (and team) constructed a basement garage and attached ADU on the side of our 100 year old house - no small feat at all. Initially we were a little guarded because of all the horror stories you hear about shiesty contractors, but our experience with Paul has been nothing but positive throughout the entire build. He has a keen attention to detail and values good quality work. For example, there were a couple crucial details that were not described by our engineer, and Paul worked hard to determine the right course of action. In the end, what he came up with was better than we could have imagined. Not only is he personable and a knowledgeable contractor, he has an eye for aesthetic which was a delight as we discussed design options, from trim details to pergola hardware. In the end, Paul and his team built us a stunning 800 sf 2 story ADU and 400 sf basement garage, that feels spacious and contemporary while beautifully tying together with the exterior of our existing 1920s Tudor Revival home. I can not recommend Burlingame Contracting enough! Thank you Paul!!"

FAQs for addition to existing structure building service projects in Bellingham, WA
Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.
schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items.
Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.
The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic.
Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.
With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential.
This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.
Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
